hey all i was just wondering if i can use my usdm 91 si gauge cluster w/ my pr3 ecu and my 1st gen b16 swap???? i have a jdm cluster but the tach plug is missing and i have to wait for a new cluster now all for a stinking plug... well iw want to drive the car tonight and i'm trying to get away w/ useing just the usdm cluster for now.... is there wireing differences???? between the ecu's???? also will my speedo be acurate w/ the jdm mechanical vss?

 

I am using an Si cluster with my swap. Everything works fine. I just used the stock speedo cable from my dx and plugged that into the transmission.
